as the title states, if i save when I have a vanilla or altered vanilla summon spell creature out, I cant load that save. Normally i can avoid it but since the game crashes alot I do rely on quicksave autosave and regular saving at regular intervals so this is a real pain. I got too many mods to list, but the ones worth mentioning are SM, FCOM, Midas, deadly reflexes, kobu's, Beauty pack.

any help?
